Hi wout -
<br>
<br> The childish tactics you have so often used on the open forum of partial information and misdirection really do not belong here -
<br> THIS IS THE 20 --REPEAT 20 --FORUM --for20 rules discussion including some concepts you may not comprehend or agree with ,on a size cat that you obviously do not sail , you bring your 16 ht bias , but this is not the way to promote 16s or encouage activity in it .Most have very serious reservations about your motives .-This does not help .
<br>
<br> We all understand basic measurements of length beam weight and sail area ,--weight effects wetted surface area -
<br> {static } --that is why 16s have favorable numbers ,--lightweight in comparison to heavy -420 lb iF 20 cats.
<br>
<br>-there is no great mystery here , though do appreciate the partial information and conclusions provided.
<br>
<br>-add 2 large crew gear and equipement {added weight }to a 16 and thrust of sails and numbers begin to vary .
<br>
<br>-Of course a smaller boat with better sail area to weight ratios like the A-Class ,--150 boat weight =150 sail area ,-will have a performance curve and ideal set of conditions where it performs ideally that overlap others , faster in that particular set of conditions , again we appreciate the testimonials thoughtfully provided .
<br>
<br>-This is the basis of the weight to sail area scale ratio proposed -FOR 20S -
<br> Existing heavier cats are allowed more sail area ,--the existing N-6/0 WITH LARGE existing 268 sq ft of main and jib and 348 SQ FT chute raced by many active racing N A sailors at the top end ,--down to a 320 LB 20 ft cat at the other end with SMALLER sailplan than existing iF 20S in a graduated scale . -An interesting performance curve within the 20 class from light air to heavy.
<br> Again something you totally misrepresented , obviously can not comprehend , -therefor your need to deconstruct , Does the prospect of equally lighter high performance 20s really threaten your percieved 16 agenda to this extent .
<br>
<br>-Lets give it a rest and on to more productive endeavors -
<br> We need 16 -18-and 20 classes -
<br>
<br>-this just in on the 18 NA Formula class-

<br>Welcome to the North America Formula 18 Class website.
<br>
<br>Welcome to the North American Formula 18 Class Association website. Our purpose is to promote racing of ISAF Formula 18’s (F-18) in North America. We plan to race ISAF-18 compliant boats with simpler measurement rules and one jib size under a new class called the North American Formula 18 (NAF-18).
<br>
<br> Due to the much greater distances between fleets in North America, lower average winds speeds, smaller fleets and generally lower population densities, we believe that it is necessary to modify some of the F-18 rules for use by the NAF-18.
<br>
<br> The primary modification that we have made to the F-18 rules is the use of prototype boats and sails to control compliance with F-18 weight and dimensional requirements in NAF-18 boats. This shifts the onus of compliance with F-18 dimensional and boat weight requirements from the individual boat owner to the manufacturers. We have done this to eliminate the need for class Measurers in North America. The objective is to keep the cost of boats and regattas down by eliminating the cost of measurement for each individual boat and set of sails and by reducing the number of points that may be measured at an NAF-18 regatta.
<br>
<br> We plan to use the larger 4.15 m2 F-18 jib for all NAF-18’s rather than having a smaller 3.45 m2 for lighter crews and the 4.15 m2 for heavier crews. We have made this change to keep the cost of sail development down and because the smaller jib has little effect on boat speed.

<br>Who we are: In early August, I started talking to Chris Herman about starting the F-18 class in North America. F-18 Class being a huge success in Europe for at least eight years, we decide to give it a shot. By October, Tom Liston jump in an got involved in the rules. Matt Stuble volunteered represent the Northern Area, the small committe decided Matt would be a great addition to the new class. Finally after all the re-rights the provisional rules are now posted. We also recieved input from appx. 20 sailors, across the country....330 hits on the new web page that hasn't been made public until now. We still have a work ahead....
